My program is suppose to count the occurrence of each character in a file ignoring upper and lower case. The method I wrote is:

public int[] getCharTimes(File textFile) throws FileNotFoundException {

  Scanner inFile = new Scanner(textFile);

  int[] lower = new int[26];
  char current;
  int other = 0;

  while(inFile.hasNext()){
     String line = inFile.nextLine();
     String line2 = line.toLowerCase();
     for (int ch = 0; ch < line2.length(); ch++) {
        current = line2.charAt(ch);
        if(current >= 'a' && current <= 'z')
           lower[current-'a']++;
        else
           other++;
     }
  }

  return lower;
 }

And is printed out using:

for(int letter = 0; letter < 26; letter++) {
             System.out.print((char) (letter + 'a'));
       System.out.println(": " + ts.getCharTimes(file));
            }

Where ts is a TextStatistic object created earlier in my main method. However when I run my program, instead of printing out the number of how often the character occurs it prints:
a: [I@f84386
b: [I@1194a4e
c: [I@15d56d5
d: [I@efd552
e: [I@19dfbff
f: [I@10b4b2f
And I don't know what I'm doing wrong.
